Wolves took the lead through a Bakary Sako penalty before Nouha Dicko wrapped up the win with a powerful finish.

After the game, Karanka said: “The person who made the first mistake was me because I didn't chose the right players to play.

"I am the person who made the first mistake and after that we couldn't play in the way that we wanted to play.

"We didn't play like we know we can play, we didn't play with the right intensity."

The Boro boss declined to say which selections he got wrong, but did add: “I am disappointed but they were better than we were.

"I told the players this week that Sako and Dicko would be dangerous and showed them videos to demonstrate where they were strong, but we didn't cope with them, we couldn't stop them and they scored both of the goals.

It was former Wolves defender George Friend who committed the 32 minute foul on Dicko that led to the penalty.

Asked if he thought it was a fair decision by the referee, Karanka said: “For me it is not important because they were better than us and they deserved to win the game.

"The most important thing for me is I am disappointed because lost the game in the way we knew we would if we didn't play well.

"We knew where they would be strong but we didn't deal with that threat.

"We knew they were a good team, I knew they would play with a high intensity and we knew that if we wanted to do something against them we would have to play with the same intensity but we didn't do that.

"Now it is important to focus on the next game against Watford on Saturday."
